Fig. 8 is a horizontal section of the pump cylinder on the line T T, seen in Fig. 1, looking downward. Fig. 9 is an end vievv of a portion of the engine and of the spring adjusting means.

Referring to Fig. l, the uprights 1 and 2' are tormed with base 3 and form the supports for the engine. On upright 1 is formed the bearing 1, in which drive shaft 4 is rotatably mounted. Elaid bearing is provided with cap l". Drive pulley 5 is secured on the outer end of said drive shaft, and hub 6 is secured on the inner end thereof. Drive hub 6 has hub chamber 6 formed therein and opening 6 formed through the outer end thereof, leading into said chatn her; .Said hub is secured on. the open end of crank case '1 and forms one end thereof. The right end 7' of said crank case has hub 1 formed therewith, which latter is rotatably mounted on fixed crank shaft 8. Said rank case has the pump cylinder 9 and powencylinder 10, formed therewith and opening into said case. Crank shaft 8 is secured. @110 upright 3 by cap. 8 pressed firmly on the.fiat face 8 of said shalt, by cap screws 11, (see Fig. 9) screwed into upright Referring to Fig. 1, hub chamber 6 is -,connnunicatively connected with the outer end of pump cylinder 9 by pipe 12 and elbow 12 secured to said cylinder. Said hub chamber is similarly connected by pipe 13 with colupr esslmi chmnber 14; secured on power cylinder 10 and communicatively connected with said cylinder by cylinder inlet ports 15, formed through the wall of said l3 is extended from said com n-ession chamber and has its outer end closed and secured to cylinder 10 at 13. Port plate 16 is secured on the end of huh (3 and has port 16 formed l'l)C1'(.l-lllf()HLifll,- won best in Fig. 11-. .llotatably mounted on (h'ivo siniij't l, lllKi against said port plate is the port 17. Said gate has gate port 17 formed on the periphery thereof. is engaged with worm l8, rotatably mount- 'ed in bracket bearings 19, secured on upright 1, seen best in Fig. 3. Said worm is .provided with hand wheel 20, having retaining notches 20 formed in the periphery thereof. Said notches are engaged by the -fre'e end of retaining spring 21 for detachably holding said hand whee. The other end of said spring is secured on one of the v brackets 19. a Referri to Figs. 1 and 5, mixture inlet chamber 22 is rotatably mounted on shaft 4, and has chamber port 22' formed through one end thereof, said chamber being adapt ed to be adjustably opened and closed by the rotation of the previously described port gate. Said inlet chamber has a connection formed therewith, said connection being adapted to have an ordinary carbureter, not shown, connected therewith, for mixing and admitting an explosive mixture of fuel and air through said connection into said mixture inlet chamber. Said chamber is held against rotationby screw 23, assed through the lower flanged edge 0 said chamber and screwed into upright 1. The outer end of drive hub 6 and theadjacent surface of port plate 16 are so shaped as to form an annular channel 24 in which the electrode ring 25, carrying electrode 25 is rotatably mounted. Said electrode is adapted to be rotated into and from contact with fixed electrode 26, secured on insulation 26', secured on inlet chamber 22.

Referring to Fig. 1, the electrode ring 25 is connected with the free ends of the centrifugal governor arms 27, by connecting rods 28. The other ends of said arms are pivotally secured to hub 6, and are provided with projections 27 to which the free ends of 40 springs 29 are secured. Said springs are each provided with tensioning nuts 29? and are thereby properly tensioned to resist outward movement of arms 27. The inwar movement of said arms is limited by contact of the free ends-of same with hub 6.

Referring to Fig. 1, hub, spring chamber 30 formed therein, in the inner end of which are the bearing balls 31, against which washer 31 is pressed by spiral spring 32, compressed bywasher 33,

screwed through cap 8, and by screw 35 screwed through the upper .end portion of upright 3; thus providing elastic pressing means, whereby the face of port plate 16 is firmly pressed against't-he face of port gate 18, for automatically taking up such space between said plate and gate as may be caused by wear of same, and at all times firmly keeping said faces in contact.

Referring to Fig. l, fixed crank shaft Shas crank wrist 36 formed therewith, said wrist being connected with power piston 37, by our ecting rod 38. On the wrist connected 65 end of said rod is secured the'wrist pin block the usual well known manner.

into and from mixture through the carbureter,

into hub chamber d .into compression chamber 14, from whence through ports 15, into 7 has annular adjusted in said pressure by screw 34 ton 11 by connecting. rod 12. In operation,

the described connecting rods are rotated on fixed crankwrist 36, from the position seen in Fig. 1, to the position seen in d by the .his rotation of said rods'is cause hereinafter described rotation of cylinders 9 and 10, which are further rotated until all V of the rotatingparts are moved from the positions seen 111 Fig. 2, to the positions seen in Fig. 1, thereby reciprocatively moving said pistons in their respectivecyl-inders. A plurality of exhaust ports 43 are forme through the wall of power cylinder 10, opposite to the previously described cylinder inlet ports 15, seen best in nary electric spark plug 4.4: outer end portion of said power is secured in'the Said plug carries'the plug electrode 44',

cylinder in.

contact with fixed secondary electrode 45.

Said electrode 45 is secured to insulation 46, secured to upright 1. Crank shafh8 has oil duct 47 formed longitudinally therethrough and elbow 48, connected with the outer end of'said duct.

In operation, cylinders 9 and 10 are manually rotated in the direction indicated by arrow 19, for starting the engine. During said rotation, pump piston 41 draws a charge of the previously described explosive not shown, into inlet chamber 22, thence through cham ber port 22, gate port 17, plate port 16 and hub opening 6", into hub chamber 6, thence through pipe 12 and elbow 12, into cylinder 9. At this point in said rotation,

ort 16 is rotated past register with gate port 17, and the thus confined charge is compressed through said elbow, and pipe 12 6 thence through 'pipe 13 said charge passes power cylinder 10, while power piston 37 is passing through the inward port-ion of its rotation, as seen in Fig. 2. Continued manual rotation of said cylinders brings the parts to the position seen in Fig. 1, causing power piston 37 to compress said charge in cylinder 10. At this juncture electrode 25' is moved from contact with electrode 26, (see also Fig. 4,) thus closing and opening a primary electric circuit, (not shown,) in the usual well known manner; thereby causing a secondary electric impulse to pass through secondary electrodes? and plug electrode 4st, the metallic portions of said engine and a secondary electric circuit, not shown; thereby producing an electric spark at the inner end of electrode 44', thereby igniting said charge. The ignition of said charge provides energy said cylinders are caused to rotate and the described operations are repeated. As the spark by which- .used, the free end of spring 21 is manually lifted from notch wheel 20 is manually rotated in either direction, gate 17 is rotated by thedescribedworm gear and worm, un-

' til the opening through inlet chamber port 22 is reduced or increased bx the rotation of said gate'as desired.
